Need a Cars shirt design

I've dug and dug and had no luck finding this so far. I'm wanting to make a shirt for a young boy named Rhett making his very first trip to WDW. He's a big Cars fan, so I was trying to find a Cars theme or maybe a mickey shaped head with Cars background? Any help is much appreciated!
